Below are sample questions representative of the exercises included on this worksheet and related 7.62 Population, Consumption, and Earth Systems skill assessments:

Problem 1Difficulty: Mastery

A city’s climate plan sets two targets: (1) reduce per-person emissions 30%, (2) grow population 15% by attracting new jobs. The city wants total emissions to fall 20%.

Which statement is best supported by math-based evidence reasoning?

ATotal emissions will stay exactly the same.

BTotal emissions will definitely increase.

CIf per-person emissions fall 30% and population rises 15%, total emissions will fall, but not necessarily by 20%; totals depend on multiplying the changes.

DPopulation growth does not affect totals.

Solution & Explanation:Total emissions ≈ population × emissions/person. A 30% drop means ×0.70, and 15% growth means ×1.15. Multiplying gives 0.70×1.15=0.805, about a 19.5% drop—close to 20% but you need the multiplication to check, not guess.

Problem 2Difficulty: Mastery

A region’s total fish catch fell 15%. Over the same period, the number of boats rose 10% and sonar technology improved. Surveys show fish populations declined 20%. "

Which claim is best supported by the evidence?,A. Improved technology guarantees fish populations increase. | B. The decline in fish populations is consistent with overharvesting pressure increasing (more boats and better technology) relative to the resource. | C. More boats always means more fish. | D. Fish populations are unaffected by fishing.,B,More boats and better technology can increase fishing efficiency

Solution & Explanation:Consumption

Problem 3Difficulty: Mastery

A region restored a forested watershed and protected it from development. Over time, the cost to treat drinking water decreased because less sediment entered the water supply.

Which claim is best supported by the evidence?

AForests increase sediment in water supplies.

BProtecting ecosystems can reduce the need for costly human-built treatment by keeping water cleaner naturally.

CWater treatment costs are unrelated to land use.

DEcosystem protection always increases pollution.

Solution & Explanation:After protecting and restoring the watershed, sediment decreased and treatment costs fell. That supports that healthy ecosystems can provide services (like water filtration) that reduce human costs.
